Pseudomonascattleyae is the correct name if this species is regarded as a separate species within a separate genus Pseudomonas.
Because the type strain of Pseudomonas cattleyae (Pavarino 1911) Savulescu 1947 (Approved Lists 1980) is allocated to Pseudomonas avenae subsp. avenae Manns 1909 (Approved Lists 1980), Hu et al. 1991 propose Pseudomonas cattleyae (Pavarino 1911) Savulescu 1947 (Approved Lists 1980) as a later heterotypic synonym of Pseudomonas avenae Manns 1909 (Approved Lists 1980).Publication:
